Title: Boom point sheave assembly
IPC: B66C23/66
Filed: 1976-05-20
Abstract: 1501076 Sheave assembly RUSTON-BUCYRUS Ltd 20 May 1976 [21 May 1975] 20958/76 Heading B8B A boom point sheave assembly for the boom 1 of a materials handling apparatus comprises a sheave shaft 13 which extends transversely of the boom point 3, is pivotally mounted at its centre in the boom point 3 about an axis transverse to the shaft 13 and extends to each side of the boom point to rotatably mount a sheave 7. The tip of the boom point 3 includes a socket 10 in which is clamped a bearing seat 11 having an opening transverse of the point 3, the sheave shaft 3 extending through this opening and having cammed outer surface at its mid-length position pivotally engageable with a similarly shaped cammed surface at the mid-length point of the bearing seat interior. Pivoting of the sheave shaft 13 is restricted by diverging abutment walls within the bearing seat at each side of its curved bearing surface, which engage the outside surface of the shaft 13 at each side of its cammed bearing surface after a predetermined angle of pivot. A torque rod 18 is secured at one end 19 to the boom point structure and at its other end is in keyed engagement with a cross shaft 20 which extends transversely through the sheave shaft 13 and is keyed thereto at 23. The torque rod 18 therefore tends to resist pivoting of the shaft 13 and returns the shaft to its normal positions when the pivoting forces, caused by off-lead actions of load ropes passing over the sheaves, are relieved. Each sheave is mounted at its shaft end on a bearing 17 retained by elements 15, 16 and a protective cover 14 is mounted about the sheave shaft 13 and the bearing seat 11 on each outer side of the bearing seat. In the embodiment of Fig. 5 (not shown) two boom points are formed on a common boom and each point mounts two sheaves as previously described.

Title: Improvements in pulling-over machines
IPC: A43D13/00
Filed: 1920-07-13
Abstract: 170,352. Riesz, I. July 13, 1920. Lasting and pulling-over -In a pulling-over machine of the type in which the pincers, after having stretched the upper over the last, return in a closed condition against the insole to lay the margin of the upper upon the insole, the pincers are held in the upper - stretching position by a ratchet mechanism allowed to move reversely after the upper stretching movement - so that the closed pincers may approach the last bottom. As shown, side pincers 20, Fig. 3, are connected by an equalizing- lever to an arm 16 and toe pincers 5 connected to a similar arm 17, both arms being pivoted on a shaft 15. The arms 16, 17 are connected by links 13, 14 with band brakes 8 on a rotating shaft 1, the bands being tightened by pedals 9, 10 to stretch the upper. The arms 16, 17 are each provided with a gear segment 51 meshing with a spur wheel moving with a ratchet 47 provided with pawls 45 for holding the upper in the stretched position. The pawls 45 may be raised when required by a lever 54 and are carried on a bell-crank lever 41, 42 pivoted on a shaft 2, the arm 42 having a roll 43 engaging a cam 44. When the stretching is complete, the operator engages a clutch driving the shaft 2 through one revolution. The shaft 2 carries cams producing indraw of the pincers, bringing down a hold-down on the toe of the last, and moving the cam 44 to allow the ratchet mechanisms to return. The lever 41, 42 is connected to the shaft 2 by a yielding coupling comprising a spring 84, plunger 83 and ball, to allow the lever to lag behind the shaft until the cam 44 has been moved out of the way of the arm 42. The toe-stiffener has a support 109, Fig. 8, pivoted so that it can yield when engaged by the pincers in their inward movement. The cam-shaft 2 is driven from the constantly rotating shaft 1 by gear wheels and a clutch 60 operated by a handle 3, which simultaneously brings into action the hold-down 85. A gapped disc 67 on the shaft 2 co-operates with a roller 66 actuating a gear segment 65 engaging a rack 62 on the clutch operating rod, to keep the clutch in engagement for one revolution of the shaft 2 and then disengage it. The hold-down incorporates a spring and presser-foot independently adjustable, and is operated by a cam 100 after its initial movement by the handle 3. The pincer-carriers are provided with tack-driving mechanism fed with tacks from tubes 115. Fig. 3, when the pincers are in their outward position. As the pincers move outwards, chins of leather are removed bv a brush 116 automatically lifted as the pincers return by a pivoted spring-pressed stop 120 engaging a cam 121. The upper mechanisms are mounted on a table pivoted at the rear to the machine frame, so that after disconnecting various links the table may be tilted upwards and backwards to give access to the mechanism.

Title: Improvements relating to the manufacture of sulphate of ammonia from gas works liquor or the like
IPC: C01C1/242
Filed: 1927-08-16
Abstract: 299,934. Robson, S. Aug. 16, 1927. Ammonium sulphate is prepared from crude ammoniacal liquor such as gas-works liquor by distilling the said liquor to free it from non- volatile nitrogen compounds, concentrating the distillate, if necessary, to an ammonia content of about 6 per cent, then volatilizing the distillate at a temperature such that the proportions of ammonia gas and water vapour in the resulting gaseous mixture are correct for combination with sulphur tri-oxide to produce dry neutral ammonium sulphate, and then treating the gaseous mixture with sulphur trioxide to produce ammonium sulphate. For a dry neutral salt, the ratio of NH3 : H2O is approximately 2 : 1, and the salts may be collected by bag-filtration devices, electrostatic separators or other collecting means. The temperature necessary for the volatilization may be ascertained by determination of the partial vapour pressures of ammonia and water over various mixtures at varous temperatures. Specification 289,950 is referred to.
